ABSTRACT
<p><b>OBJECTIVE</b>To acquire sufficient PDGF-BB protein and provide the basis for the further studies of its role on the fracture healing and trauma reconstruction and its clinical applications.</p><p><b>METHODS</b>Constructed the prokaryotic expression vector pQE-PDGF-B with the gene rearrangement technique, and the monomeric form of recombinant PDGF-B expressed in E. coli M15.</p><p><b>RESULTS</b>PDGF-B mature peptide gene was inserted into prokaryotic expression vector pQE30, which was confirmed by PCR, enzyme digestion and sequencing identification; the expressed products of pQE-PDGF-B in E. coli showed a single protein on SDS-PAGE, and their expression level was about 15% of the total bacterial protein. The molecular weight of the purified PDGF-B protein was about 15 KDs on SDS-PAGE.</p><p><b>CONCLUSIONS</b>The construction of recombinant plasmid and preparation of the monomeric protein of PDGF-B provides a solid foundation for further studying the function of PDGF-BB and producing biologically PDGF-BB protein.</p>
